Centreon Infra Monitoring

=============================================================================================== ENGLISH (FRENCH BELOW) ===========================================================================================Hello,I expose my problem here hoping to find some help...I noticed a rather strange behavior on my Centreon, I connect via LDAP.If I make a single login/password mistake, my AD account is instantly locked.On the AD side, the locking policy is 3 attempts and the problem is only encountered with Centreon.Real example:Here we can see 3 attempts with failure, except that I tried to connect only once.As if Centreon retries several times by itself? ==================================================================================================== FRENCH ======================================================================================================Bonjour,J’expose mon problème ici en espérant pouvoir trouver de l’aide…J’ai remarqué un comportement assez étrange sur mon Centreon

Hello, i wondered if there was a CLAPI query to get the top counter values from a centreon. I am not running the latest version so i’m unsure that it is available in the web API or the CLAPI.Do anyone know what could be used to get this data programatically ?

 Hello everyone Ive tried connecting my poller to the centreon central server and tired debugging and I see nothing wrong on the poller side nor the central server side, ive retsrated cbd, centengine, gorgoned, ive exported and imported config files, ive restarted the services on both vms, etc. I cant seem to figure out what’s wrong now, however i do see this log in the debug of centreon central, something about a key that changed?and Ive tried checking the ip tables and netstat connections etc and the result below is what i got, appearenlty the central is trying to connect to the poller but the connection gets refused or soemthing, and no the firewall isnt issue nor is the SElinux. Update:Ive changed the fingerprint in the hsitory.dsb file from the old one to the new one, now when I run the netstat command the connection is established in the centreon central, but now the poller has the same “TIME_WAIT” thing that i had in the central earlierresult in the central , Im not sure what TI

Hi everyone,I’m encountering an error with the centreon_cisco plugin while trying to monitor memory usage on a Cisco CBS350 switch (firmware version 3.4.0.17): UNKNOWN: Cannot find memory informationsHas anyone experienced this issue before? If so, are there known workarounds to retrieve memory metrics?Details: The plugin fails to fetch memory data via SNMP. A custom script workaround might require privilege level 15 (full admin access), which is restrictive. Questions: Is there a specific OID for memory monitoring on CBS350 switches running firmware 3.4.0.17? Are there alternative methods to monitor memory without requiring privilege level 15? Any insights, scripts, or configuration tips would be greatly appreciated!Thanks 

Hi,I am trying to add a check on a web page to ensure it is up and running. I tried with the HTTP plugin with the HTTP-Response-Time service template. By default it will fail only if the web server is not responding but it will be OK even with a 404 error for exemple. So I guess I have to use the option --critical-status to check that return code is 200. This gave me the following command/usr/lib/centreon/plugins//centreon_protocol_http.pl--plugin=apps::protocols::http::plugin--mode=response--hostname=myhostname--proto='https'--port='443'--urlpath=''--warning=''--critical=''--http-peer-addr='my_web_page_url'--critical-status='%{http_code} != 200'However when the web page URL returns a status different from 200 the test is still OK.I guess I should use a different syntax for the --critical-status parameter? But all the exemples I found refers to this syntax.I might have to use a different plugin or template to do what I seek? But I could not find which one then.Your help or comments are

Hello,I’m looking for someone to help me install remote connectors on a centreon centralI try to follow documentation but each time, unable to connect the remote to the central after the installation…Someone available to make it together on Discord or other please ? Very big thanks !

Hi everyone,I'm using the open source version of Centreon (no license, no commercial subscription) and I would like to monitor equipment like Cisco switches, HP servers, UPS, PDUs, etc. using SNMPv3.I know that with a commercial license, I could simply use the Monitoring Connector Manager to install packs like network-cisco-standard-snmpv3, but in the open source version, only basic modules are available and the rest require a license.That said, I was able to install centreon-pack-operatingsystems-linux-snmpv3 via APT, and it works perfectly for Linux hosts using SNMPv3. So I assume it's technically possible to use SNMPv3 monitoring for other devices as well, but manually, without licensed packs.I’ve already cloned the official centreon-plugins GitHub repo and I can run checks via CLI successfully. How should I configure them properly in the Centreon web interface (host templates, service templates)?This is part of a large-scale migration from SNMPv2 to SNMPv3 across many existing devi

Hey everyone,I’m setting up Centreon and I’ve hit a point where I’m confused about how Monitoring Connectors, plugins, and the GitHub plugin repo all relate — especially when it comes to licensing and offline environments.Here’s my current situation and questions: After a fresh install of Centreon, I could install some Monitoring Connectors (I think these are the default/free ones). But I also see many others greyed out — I assume those require a license? I understand that Monitoring Connectors (or Plugin Packs?) are templates that help configure services, but I’m not sure how they relate to the actual plugin scripts (like those in /usr/lib/centreon/plugins/). I also don’t really get the relationship with the GitHub repo (https://github.com/centreon/centreon-plugins). Can I just clone that repo and use it without a license? if I clone it will i be able to use all plugins and won’t need to install connectors/packs etc? If I do clone the GitHub repo, should I clone it on the Centra

Bonjour, Nous avons fait un backup de notre serveur Centreon avec les paramètres suivant :Jusqu'à la, pas de souci.  Cependant lors de la tentative de restauration sur une autre machine avec configuration identique (même debian / même version de centreon / même paquet d’installation), nous avons une impossibilité de se connecter, pas de message d’erreur.Le pas à pas suivi est présent sous ce lien : https://docs.centreon.com/fr/docs/administration/backup/Nous sollicitons votre aide!Anthony

Bonjour à TOUS.Nous avons besoin de votre aide et de votre expertise.Nous avons pour projet de rapprocher plusieurs serveurs centreon afin de regrouper les informations.Après plusieurs tentatives infructueuses, je n’arrive qu’a exporter les données de mon centreon A vers mon centreon B ou inversement mais les données qui sont exporter ne sont plus accessible sur le centreon initiale. (si A envois vers B, les données de A sont visible sur B mais les données de B ne sont plus accessibles et si B envois vers A, les données de B sont visible sur A mais les données de A ne sont plus accessible)  Peut-on récupérer les informations de plusieurs centreon en 1 mais conserver leur indépendances? Merci d’avance  Hello everyone.We need your help and expertise.We have a project to bring together several Centreon servers in order to consolidate the information.After several unsuccessful attempts, I can only export the data from my Centreon A to my Centreon B or vice versa, but the exported data is n

Hello,I'm running Centreon and trying to use the plugin hardware::hds::csu::rest::plugin  (internally developed but issue is not related to the plugin) to monitor an HDS storage system via REST. However, I'm getting the following error when executing the plugin manually:UNKNOWN: Can't call method "add_options" on an undefined value at /usr/lib/centreon/plugins/centreon-plugins/src/centreon/plugins/http.pm line 32.Here's the command I'm running:perl /usr/lib/centreon/plugins/centreon-plugins/src/centreon_plugins.pl \ --plugin=hardware::hds::csu::rest::plugin \ --mode=alerts \ --custommode=api \ --hostname=xxxxxx \ --username='localhost\xxxxx' \ --password='xxxx' \ --csuid='4c4c4544-0046-4210-8033-b8c04f335732' \ --ssl-opt='SSL_verify_mode => SSL_VERIFY_NONE'Additional notes: All required Perl packages (e.g. perl-libwww-perl, perl-LWP-Protocol-https, etc.) are installed. Basic plugin tests like check_ping or check_memory work fine using the same Perl binary and environment.

Hi all,I'm trying to use the Centreon plugin for VMware (apps::vmware::connector::plugin) on a poller running RHEL 9 / AlmaLinux 9. The plugin fails with the following error: UNKNOWN: Cannot load module --custommode. Can't locate ZMQ/LibZMQ4.pm in @INC (you may need to install the ZMQ::LibZMQ4 module) (@INC contains: /usr/lib/centreon/plugins/centreon-plugins/src ...) I installed zeromq and zeromq-devel from the default system repo, which provides version 4.3.4. However, ZMQ::LibZMQ4 requires libzmq headers to compile, and Centreon’s own repo (centreon-24.10-stable) provides zeromq-devel-4.3.5, which conflicts with the system-installed version: Error: Problem: package zeromq-devel-4.3.5-1.el9.x86_64 from centreon-24.10-stable requires libzmq5 = 4.3.5-1.el9, but none of the providers can be installed - libzmq5-4.3.5 conflicts with zeromq 4.3.4 from @System Since Gorgoned is already running using the system version of zeromq, I don't want to risk breaking it by replacing it.I’m not sure

Hi,I have recently installed Centreon 24.10.7 on premise on Alma linux 9.5A temporary 60 days license was provided and installed. On the page: Configuration  >  Connectors  >  Monitoring Connectors the message “No monitoring connectors found” appears.  The online documentation says:install the Monitoring Connectors repository (go to the Centreon support portal for its address) Obviously, without the repository the installation isn’t possible:# dnf install centreon-pack-*Last metadata expiration check: 7:24:42 ago on Wed May 14 06:48:52 2025.No match for argument: centreon-pack-*Error: Unable to find a match: centreon-pack-*  Could you provide me the repository details? Regards,PerBacco 

Hello, I'm asking for your help because I recently installed a new Centreon server in version 24.10.7 on a Debian 12 and I'm constantly getting errors for various things that I encounter only in HTTP and never in SSH, in particular for creating a Host. When I want to create one via Web UI and I click on the “Save” button to register my new host, nothing happens and my centreon WEB interface crashes for a few dozen seconds.Another thing is that when I perform various other actions, I constantly get the following messages: “failed to fetch” “Oops, something went wrong” at the bottom of the page. Any idea where this might be coming from?I'm also attaching the source code inspection with Google CHROME to show you the type of error that keeps appearing.Thanks in advance.  

Hello, I have an issue with Backbox Plugin and I don’t know if someone experienced the same.For “Backup” mode, all is ok, So API Token is validated :-)But for “Device-Backup” and “ConfigStatus” modes, I have a “404 not found” issue. In command Line, for “Device-Backup”, I thnik there is an issue related to urls in plugin.It does a GET on 2api/devices” and give a result:But just after, try to join “/rest/data/token/api/devices/dynamic”and this 2 times… I don’t think “Dynamic” exists.Maybe someone experienced this??? Regards, Laurent

Hello,I have around 1000 VMs which I added initially into host groups like prod, preprod, uat etc. The VMs are a mix of windows and linux. Now since I will be using snmp templates and some will use linux_snmp and some will use windows_snmp templates, I want to create 2 new host groups - windows and linux. Now I want to add my hosts into these host groups. What would be the easiest way to do it please? via csv import for example. How to add my already added hosts to these new groups without impacting the existing hosts or host groups. For example, I cannot delete and readd all hosts with updated host groups. I dont have autodiscovery license.
